Provisioning with Oracle Cloud Stack Manager
2 likes742 views
The document discusses the fully automated provisioning of Oracle Cloud services using REST APIs, emphasizing the benefits of consistency across various environments and time savings for administrators. It introduces the concept of an Oracle Cloud Stack as a way to manage multiple services as a single unit and details the use of templates for standardizing cloud service instances. Additionally, it provides insights on creating custom templates to meet specific customer requirements and highlights essential tools and tips for successful stack management.

All rights reserved. | Confidential FULLY AUTOMATED PROVISIONING OF CLOUD SERVICES • We can already fully automate provisioning of Oracle Cloud services from command line using REST APIs • It’s a good thing to do as most organisations have more than one cloud environment: – Consistency across dev/test/production environments – Should save administrators time overall – Reduces the reluctance/inertia for creating new environments – Automated provisioning can be part of CI/CD pipelines (especially with metering like Universal Credits) 2

All rights reserved. | Confidential FULLY AUTOMATED PROVISIONING OF CLOUD SERVICES • A cloud environment typically consists of several of the following: – Storage containers for backups – SSH keys – PaaS instances, such as databases • Cloud console screens simplify provisioning but are still lots of parameters to enter – E.g. 47 (some duplicates) for a 2 node SOA CS cluster and a single instance database • Most organisations have a limited number of platform patterns (e.g. clustered, non- clustered, large, small) with a few parameters to distinguish them: – ID (e.g. number) – Tier (dev, prod, etc) – Environment pattern – Front-end details3 My goal is (after customer setup) to only need these parameters for any new environment creation

All rights reserved. | Confidential WHAT IS AN ORACLE CLOUD STACK? • Intended for multiple services (“stack”) but can use for just one – Why would you do build a “stack of one”? • To simplify • To standardise • Even one service has dependencies, e.g. storage • Can simplify provisioning, especially from console – Will be even better if/when parameters can be hidden 8

Oracle-supplied templates cover lots of products and are a great starting point, but… • I wanted to change: – IP Networks instead of Shared Network – Separate backup containers – VM flavours (e.g. high memory usage) • Plus I had customer-specific requirements: – To enforce standards – To minimise env-specific information needed (e.g. have standard storage user & DB SID naming) 13

All rights reserved. | Confidential CLOUD STACK MANAGER TIPS • You have to install PSM first – try Windows Subsystem for Linux #WSL ☺ • As ever don’t try to change too much at once • Use an editor with a YAML syntax highlighter / linter • Template is a one-use starter – can change later without affecting instances • Use Oracle-supplied (or free oracloudprov) templates as a starting point • Note: when delete a Cloud Stack it doesn’t delete object storage – tidy up yourself, e.g. with REST API 17

All rights reserved. | Confidential SUMMARY • A cloud stack is a set of Cloud Service instances, managed as one • Stack manager can easily cut down number of parameters you need & improve consistency • Cloud Stack Manager is production-ready for many types of Cloud Service types Remember: Cloud Stack is not silver bullet for all automation – you still usually need to automate customer-specific configuration of platform (e.g. TLS certificates) 18
